Current Question (ID: 12714)

Question:

A centriole-like structure, from which the cilium and the flagellum emerge, is the:

Options:

1. Centrosome
2. Basal body
3. Axoneme
4. Vimentin

Solution:

The structure from which the cilium and the flagellum emerge is the basal body. The basal body is a centriole-like structure found at the base of cilia and flagella in eukaryotic cells. It is responsible for anchoring the cilium or flagellum to the cell and providing structural support for its movement. The basal body has a similar structure to the centriole, with microtubule triplets arranged in a 9+0 pattern. The axoneme is the core structure of the cilium or flagellum, composed of microtubules and dynein arms that are responsible for the movement of the structure. Vimentin is a type of intermediate filament protein found in the cytoskeleton of eukaryotic cells, but it is not directly involved in the formation or movement of cilia or flagella.
